You can choose to be your own character, or one of them already here.

In a large 3 story house, A group of people gather. They don't know by they're there, or how they got their, but they don't care. It's pretty relaxing there anyways...

Frisk, Kris, The Knight, and Hat kid all sit on a couch

Chara looks over at the 4 silent people all gathered on the couch

Chara: Weirdos.

Niko: I wonder why they don't talk much?

Sans: probably because they're too shy or something like that.

Peppino: Yeah, no kidding-a.
